Hi All,
I am using the ant installer in its Non-Extractor mode. I use the java -jar command to start the installer. After this the UI is displayed to the user.
What I want to do is execute a cp command, before the first UI page is displayed to the user.
Is there any way to do this? Or is it not possible in case of an ant installer?

Thanks in advance!
